Abstract: 975,411. Autographic recording apparatus. PRIMORDIAL CO. Ltd. Sept. 3, 1962 [June 8, 1961], No. 12728/61. Heading B6A. An autographic recording apparatus wherein a plurality of superposed webs are fed past an open window in the apparatus, incorporates a time-stamping mechanism operable to timestamp at least one of the webs and a manually operable knob or the like adapted to feed the webs in a forward direction only, when it is desired to record information on the webs, without time-stamping. Superposed webs 23, 28 are fed over a platen 31. The upper web 28 is fed by a roller 34 on shaft 70 and co-operating idler rollers 35, out through a slot in the casing and beneath a tearing bar 38. The lower web 23 is fed down between a time-stamping mechanism 39, over rollers 40, 41, and on to a take-up spool 42 on a shaft 43. The shaft 43 is coupled to a shaft 66 by a chain 67 passing around gears 68, 69. A gear 72 mounted on the other end of shaft 66 through a freewheel device 74, is coupled to a gear 73 on shaft 70 by a chain 71. The feed roller 34 and take-up spool are rotated to feed the webs forwardly without timestamping by a knurled disc 75 of shaft 70. A pawl 77 prevents reverse rotation of the disc 75. The time-stamping mechanism comprises a clock 44, 45, an inked web 301, and a movable stamping pad 48. The web 23 passes between the stamping pad and inked web. A thrust member 49 is pivoted at 302 on the stamping pad and is loaded to a rest position by springs 50, 51, surrounding a rod 52 fixed to the stamping pad. The springs 50, 51 engage each side of a yoke 53 on the thrust member. A cam follower 54 integral with the thrust member co-operates with a cam 55 on a shaft 56. The latter carries a disc 60 at one end having teeth 61 around only part of its periphery. Said teeth co-operate with a gear 62 on the shaft 66. To time-stamp the web 23, the shaft 56 is rotated anticlockwise as illustrated in Fig. 3. Initial rotation of the shaft rotates the take-up spool to move any writing on the web 23 clear of the time-stamping mechanism. This rotation is not transmitted to the shaft 70 due to the positioning of the freewheel device between the gear 72 and shaft 66. The time-stamping and feeding mechanisms are supported between side plates 21 interconnected by rods 16, 17. The latter are supported on lugs 14, 15. The rod 16 may be disengaged from lugs 14 and supported in a raised position by a pivoted prop 20. In an alternative feeding arrangement, Figs. 8 and 13, a single endless chain passes around gears on the ends of shafts 143, 179, and 170, Fig. 10 (not shown). The time-stamping mechanism is operated by rotating a shaft 156. A disc 160 secured to one end of the shaft 56, has a pawl 163 pivoted thereon which engages a gear 162. The latter is fixed to a sleeve 166 rotatably mounted on the shaft 156. Gear 162 meshes with a gear 168 fixed to the shaft 170. A fixed cam 171 engages the pawl over part of its travel to release it from the gear 161 during part of each revolution of the disc 160. Hence, initial rotation of the shaft 156 rotates shafts 143, 170, and 179, to feed the webs 123, 128, forwardly a short distance. A recess 161 in the disc 160 cooperates with a pivoted roller 159 to indicate the completion of each revolution of the shaft 156.
